Power supply testing system for non-utility power generators

Abstract

A power supply testing system for a non-utility power generator, etc. a plurality of tank units to be powered, which are provided depending upon the number of phases of a multi-phase AC power source used with the non-utility power generator and each of which includes a tank to be powered, having a resistive liquid filled therein, a depending main electrode located within the tank and adapted to receive a power from the non-utility power generator and a movable insulator interposed between the main electrode and the tank for regulating the amount of a current passed from the main electrode to the tank; an additional tank unit provided for spare purposes; a common unit located in communication within the plurality of tank units, in which the resistive liquids are collected from within the plurality of tank units; a main supply pipe located above the plurality of tank units to supply the resistive liquids thereto and a plurality of inlet pipes branching off from the main supply pipe into the plurality of tank units; and a flow rate regulator valve attached to each of the inlet branches for regulating the flow rate of the resistive liquid supplied to each tank unit.

What is claimed is: 
     
       1. A power supply testing system for a non-utility power generator, comprising: a plurality of tank units to be powered, which are provided depending upon the number of phases of a multi-phase AC power source used with the non-utility power generator and each of which includes a tank to be powered, having a resistive liquid filled therein, a depending main electrode located within said tank and adapted to receive a power from the non-utility power generator and a movable insulator interposed between said main electrode and said tank for regulating the amount of a current passed from said main electrode to said tank;   an additional tank unit provided for spare purposes;   a common unit located in communication within said plurality of tank units, in which said resistive liquids are collected from within said plurality of tank units;   a main supply pipe located above said plurality of tank units to supply said resistive liquids thereto and a plurality of inlet pipes branching off from said main supply pipe into said plurality of tank units; and   a flow rate regulator valve attached to each of said inlet branches for regulating the flow rate of said resistive liquid supplied to each tank unit.   
     
     
       2. A power supply testing system as claimed in claim 1, which includes three such tank units depending upon a three-phase AC power source generated by the non-utility power generator and an additional one such tank unit for spare purposes. 
     
     
       3. A power supply testing system as claimed in claim 1, wherein said tanks and main electrodes are both in substantially cylindrical forms.
